A minor detail, I know, but I’d really appreciate it if you wouldn’t call the head massager an “orgasmatron”. There are enough attempts by the media, both advertent and inadvertent, to sexualize ASMR, and we really don’t want newcommers to get the wrong idea. Those who experience ASMR may be able to easily look past the dis-analogy, but for those who don’t, it’s little things like this that make it that much harder.
I relate to much of what has been said in this conversation thread. I remember as a child, young, maybe seven… my punishment for disobedience or back talking was to stand in the corner. The corner was made by the cold wall and the refrigerator. The refrigerator was old and would kick on often blowing warm air through the crack between it and the wall. I did not know why I got tingly but I loved it and remember asking if all my punishments could be to stand in the corner. It believed it was the difference of temperatures between the wall and the refrigerator motor that caused it. Now, as an adult, I still sit over heat vents with my cheek or arm rested against the wall. I wonder why sometimes it is so intense. I get the tingles that crawl all the way down to my toes and cause a mild jerk or convulsion that sets it off again. I have synesthesia and also wonder if that serves to increase the frequency or intensity of the feeling…
For those who don't experience ASMR, it can be difficult to wrap your head around this "tingling" feeling and how something as simple as whispering or clicking could trigger it. But recent research has shown that ASMR is more than just a self-reported feeling—it can be measured physiologically. A 2018 study published in the journal PLOS One found that people who watched ASMR videos had a decreased heart rate in response, which can explain the intense feeling of relaxation many people report. Researchers also recorded higher levels of skin conductance in people experiencing ASMR, indicating arousal or excitement (likely due to the tingles).
There are deeper meanings to "bliss". As more and more people mature, process their emotions and connect with others and their true purposes, "bliss" will happen between more and more people. Basically it's asexual, a bit pleasurable but more importantly it wakes up more areas of the brain/body-complex. People processing this need to activate their bodies more in other to balance the maturing mind/spirit-aspects of their being ("grounding"), and the physical activity may also help with backpains. The tendency of such people is to be a bit too seclusive, so need to remember to assert oneself more as well.
I have definitely had this sensation many times from sexual activities, or leading up to them, as foreplay. Also while masturbating from about age 2 and up, instinctively using effleurage upon my own skin, as I comforted myself to help me sleep. I don’t see why anyone would be troubled if this phenomenon is associated with sexuality. It is undoubtedly sensual, and so is sex, so it is natural for there to be some overlap.

ASMR is described as a pleasurable tingling that begins in the head and scalp, shimmies down the spine and relaxes the entire body. Maria — she asked that her last name be withheld for safety reasons; her videos have sometimes attracted unwanted attention — experiences ASMR, and her YouTube channel, GentleWhispering, melds her personal tingle-triggers with others suggested by her fans. The resulting videos have drawn more than 87 million views, making Maria the premier celebrity of a controversial but increasingly recognized phenomenon.

While many colloquial and formal terms used and proposed between 2007 and 2010 included reference to orgasm, there was during that time a significant majority objection to its use among those active in online discussions, many of whom have continued to persist in differentiating the euphoric and relaxing nature of ASMR from sexual arousal.[citation needed] However, by 2015, a division had occurred within the ASMR community over the subject of sexual arousal, with some creating videos categorized as ASMRotica (ASMR erotica), which are deliberately designed to be sexually stimulating.[8][9]
